Q: John Galvin A: For example, if your system has a sound card and a floppy drive, you need a 178-watt power supply even before connecting a CD-RW drive. When you add the CD-RW drive, you'll need 39 watts more (30 X 1.3), but you'll lose the CD-ROM drive's 28 watts (25 X 1.3)-unless you plan to keep it installed. So your 200-watt power supply should suffice. Or try the Power Supply Selector at www.pcpowerandcooling.com. If possible, use a power supply with a higher rating than you need. A power supply with a high wattage rating minimises heat production. And that's cool. Kirk Steers |
